[Methods] The subjects included 104 upper-limbs of 52 healthy young adult males. They held the weight in 3 different positions (25, 70, 120 degrees) of elbow flexion since the previous studies reported that the 70 degrees of the elbow flexion became the longest moment arm of the biceps brachii muscle, and 25 and 120 degrees had nearly same moment arm. We measured the myoelectric activity on the biceps brachii muscle, then calculated IEMG of the interval during subjects’ holding the weight for 1 second, and normalized with a value of maximum contraction (%IEMG). For the statistical analysis, repeated measure analysis of variance was applied as well as Bonferroni method for multiple comparisons. [Results] The %IEMG in 70 degrees showed the significant low value in comparison with 25 or 120 degrees. The %IEMG in 120 degrees was significant lower than one in 25 degrees. [Conclusion] This study suggested that it was necessary to consider the influence of the difference in moment arm of the muscle when physical therapists interpreted the value of myoelectric activity of the muscle.","PeriodicalId":225008,"journal":{"name":"Japanese Journal of Health Promotion and Physical Therapy","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130606555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subjects consisted of 20 patients with knee osteoarthritis (all female, aged 63.8(cid:156)7.1 years). We assessed knee pain using the visual analogue scale (VAS) and patient-oriented QOL using JKOM. To evaluate the effects of the intervention, a baseline period (A) and a subsequent intervention period (B) were established, and measurement values were compared between the two periods (AB design). Knee pain and JKOM total score and subscale of “Pain and Stiffness in knee” sig-nificantly decreased after the 1-month intervention period (B) using adduction-reducing shoes compared with values after the 1-month control period using general sneakers (A). The results of this study suggest that knee adduction-reducing shoes are useful for reduc-ing knee pain and improving patient-oriented QOL in patients with osteoarthritis.","PeriodicalId":225008,"journal":{"name":"Japanese Journal of Health Promotion and Physical Therapy","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129870612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
